From 423e489d704d05c6e8c2927fb1854db85914912a Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Wed, 19 Oct 2005 13:06:13 -0400 Subject: [PATCH] [PATCH] hid-core: Add Clear-Halt on the Interrupt-in endpoint This patch (as577) adds a Clear-Halt call on the Interrupt-in endpoint during input device configuration. Without it my HP USB keyboard doesn't work. Vojtech says it's worth trying, since it might help with some recalcitrant devices. On the other hand, it might interfere with others. I'm submitting it so that it can get tested by a range of users.
